   My mate Dunc called round today. So into the workshop we disappeared. Between us, we finally worked out where and how the connecting rod fitted. From throttle butterfly to governor arm. There is a very light spring over this particular rod. Unfortunately one end is broken off. Something to replace at a later date. 

  The engine didn't want to start. Not even a cough. So with Dunc squirting petrol into the carb and me operating the pull start, we got it going. But the only way to keep it going, was to keep squirting petrol in.  Evidently not lifting fuel from the tank.

   After Dunc had left, I decided to take the carb off. Only three little cross head screws hold it on. Simples! Nope! Those three screws had been in there for forty years most likely. One did unscrew, but the other two needed assistance. From a small pair off mole grips for one. Mole grips, a small chisel and hammer for the other. I think three new screws will be on the things for the future list.

  I found with the carb off, the filter at the bottom of the fuel pickup pipe was covered with a film of dried dirt. This came of easily with a light brushing with a sued shoe brush. I was a bit leary of removing the tube completely, but I could blow down it and also the shorter tube next to it. That I assume is a return pipe.

  With everything back together, I tried running the engine again. Sorry to say the result was the same. Tomorrow when I get thrown out, so swmbo can get things ready for the Christmas Eve invasion of the tribe, I will have a look at the diaphragm.

As Nigel says, the diaphragm should be replaced (270026) be careful with the Spring and Pad Washer that mates up to it.

 

The Tubes with Mesh Screens on are technically both Fuel Pick ups.

The Long one picks up fuel from near the bottom of the Tank and drops it into the Internal Fuel Bowl. (it overflows back into the Tank over the edge of the Bowl) 

The Short one sits in the Internal Fuel Bowl in the Tank which supplies the Carb,

 

In order to avoid the long job of trying to get fuel up the long pipe to the Pump, you need to fill the Tank so the Internal Fuel Bowl fills.

Edit...........Shorter distance for the Intake Vacuum to lift the Fuel ......... I originally said wrongly that the Pump Diaphragm lifts it

 

The Long Pipe might well be of Brass? and not advisable to attempt removal, if Brass, the Screen at the bottom of it will pull off and you need to make sure all of the fuel tubes and capillaries in the Pump body are super clean. The faces of the Pump where the diaphragm fits must be smooth and the screws done up in a staggered sequence.

 

The Short Tube is usually Nylon and is replaceable (push in) if the mesh is rotted. Should have Hexagon base to use a socket on it to twist it out.

Suspect your Throttle Rod return Spring is discontinued, so will only be replaced by a used item.

 This morning I filled the tank as Richard suggested. Billy Goat fired up at the third pull and kept running. :woohoo:

 

Can't half fire things out. Put a rag in front of it and didn't see it come out. Stopped the engine and felt around underneath. No rag? Not surprising, as it was lying about 8ft away across the workshop.

 On the down side, I found a petrol leak. Removed the tank and there is a small pin hole in the back, halfway up. :( A couple of more suspect places as well. I'll see about having a go at soldering them up next week.

 Any other suggestions anyone?

JB weld has always worked for me and is much easier than trying to get solder or braze to take.

 

I agree with using the JB weld. I have used it on my '56 Ford 860 ag tractors gas tank in several places  that were leaking and it's still holding over 20 years later.

Clean the area, apply the product and wait 24 hours for it to completely cure out and fill up the tank. You will have a big smile, dry tank and tour wallet will be happy as well.......:)

I am really enjoying reading the progress on this and I'm learning lots along the way. Unfortunately I don't have any words of wisdom to offer.

Where from, Rhys? Somewhere like Thomas Grahams in Carlisle?

 

I've always got it locally from a motor factors, Thomas Graham may have it, but you'll get it on eBay if not.

 

Clean the area with a grinder/wire brush, degrees and apply, I repaired an escort gearbox with it which got an axle stand through it (don't ask) and it lasted until the cam belt snapped 4 years later!

  What I'm thinking is making it to mount behind, in front or even alongside of a tractor, with a pipe/tube into a trailer. Bit like a forage harvester.

Has it got enough power to blow material up the tube into a trailer? They normally have a big engine powered fan half way up do they not?

 Went to Carlisle yesterday to get some JB Weld. Stockist was shut. :rolleyes: So down to B&Q and I found a two tube epoxy adhesive similar to Araldite.

 Back home and back of tank given a good clean and a wipe with white spirit. Followed by a good smear of adhesive and then insulating tape over that. It was then left over night.

  The tank was refitted this morning and filled with petrol. No immediate sign of leakage, so I started the engine. After half an hour of continuos running all still ok.  :thumbs:

  While it was running I had a bit of a play. Throwing rags, bits of paper, coffee jar lids underneath it. I know one thing, it has plenty of umph. :D

 Had a play today. Rigged up a bit of pipe work.

  Worked quite well. Fired a rag out of the end. Took it onto the green which I'd given a topping yesterday. Didn't half shift the grass. Even the big lumps and the strips of the tractor wheels.  :D

  When I had it running in the yard, it moved under it's own power. Jet propelled.
